I know this is weirdo, but I just love it when Millie finishes eating she will give a nice burp. That is how I know she is done eating. Sometimes she will come up to me and burp.
I also love it when she snores. I know she is in a real deep sleep and she is comfortable. Millies snores all the time, too.
For such a delicate little flower, she burps, snores and farts like a truck driver.
